Hi,
I'm a new users of xen and have two questions.
The first one is that I'm looking for methods about
inter-domain communication for xen. I know besides network, VMs on the same
physical machine can exchange information by event channel and grant table. But
are these two ways working in kernel mode as part of drivers, or can I directly
use them just like network socket in user mode? I've tried to google it
but only got something I can't fully understand.
The second questions is I want to do some extra jobs
(like check tcp/ip header and change some bits) to packages in the virtual
network of xen. As all domUs' packages are passing the back driver of dom0,
I want to put this extra action to network back driver of dom0. But I'm not sure
which part of the source code has the function of receiving packages from front
driver. I think it may be function xen_netbk_tx_action. I'll be very appreciated if someone knows the
answer. Thanks!
